How does wind work?


This image, provided by Dr. Bernard Jackson at UCLA, shows the solar wind within the earth's orbit (ellipse) and coming out in a series of spokes (sectors) from the sun. The blue dot is the Earth. The spokes converge on the Sun. Note, the Earth is about to cross one of the solar wind sectors. This often triggers magnetic storms and weak aurora.

CONCEPT - group project







Our main driving force came from the idea to depict and characterize the concept of energy. We are aiming to repurpose parts from a computer mouse with the addition of turbine blades to create a wind driven installation.

Project Grid:

Content: Environmental - It is a multi faceted topic with a wide reaching range of direction and possibilities.

Input Source: RSS - Some form of Wind/Energy/Environmental Sites ie.
Using Wind Parameters such as; size of an air sample, speed, direction of motion across the world/installation city…
This will be explored further. Our RSS feed information could be sourced from the local weather site eg metservice.co.nz -

Foot Pressure Sensor Boards

So, I finally got around to populating one of my new foot pressure sensor boards with components. Once I figured out that my reflow oven controller was lying about what temperature it was reading, I just re-reflowed the board manually, watching for the solder to reflow.

The good news is, it worked fine, and it fits perfectly on the Bioloid foot as well. This board is a protoboard, and I will eventually get "proper" boards made from the same place that did my IMU boards.

Poking around inside a computer mouse

Take the lid off the KBS-835RP mouse and you see plenty of discrete components on the top circuit board. It looks positively, um, classic, compared with the surface-mount, multi-layer-board, super-integrated designs that the bigger names are using in their mouses these days.

Practically, there's not much reason to be worried about a mouse with a forest of discrete components inside, instead of a smaller number of fancier parts. There are more things that can be mis-soldered or otherwise messed up in the manufacturing process when you've got more parts, so the chance of a dead-on-arrival mouse is higher. But if the thing works in the first place, it should keep working perfectly well.

Older-style construction also, of course, means older-style components, in this case at least. That explains the A4 mouse's susceptibility to skipping when you move it quickly, and it also explains the simple two minute sleep timer.
